[0028] Please see Figures 1 to 3 This embodiment provides a connecting lock for a stage support, characterized in that it includes:

[0029] Support sleeve 1, movable rod 21, connecting rod 22, operating handle 3, ratchet fixing assembly 4, and locking buckle 5 and connector 6 for connection with stage support.

[0030] One end of the movable rod 21 is inserted into one end of the support sleeve 1, and the other end of the movable rod 21 is provided with the connector 6. The movable rod 21 can move within the support sleeve 1. The support sleeve 1 is provided with a receiving groove 11 for the operation handle 3 to move. After the operation handle 3 passes through the receiving groove 11, it is fixedly connected to the movable rod 21. Thus, by holding the operation handle 3, the movable rod 21 can be moved within the support sleeve 1, making it easier to connect the connector 6 with the stage support.

[0031] One end of the connecting rod 22 is inserted into the other end of the support sleeve 1, and the other end of the connecting rod 22 is provided with the locking buckle 5. The locking buckle 5 is used to fasten to the support rod of the stage to achieve fixation.

[0032] The ratchet fixing assembly 4 is disposed on the support sleeve 1 and is used to fix the movable rod 21 or the connecting rod 22. The ratchet fixing assembly 4 includes a screw 41 and a ratchet wrench. The screw 41 passes through the outer peripheral wall of the support sleeve 1, and the ratchet wrench is used to tighten the screw 41 to fix it. By using the ratchet fixing assembly 4, the user can operate the ratchet wrench to tighten the screw 41, thereby fixing the position of the movable rod 21 or the connecting rod 22. It can be understood that the ratchet wrench can tighten or loosen the screw 41 by repeatedly turning it within a small range, without the need for other additional tools or occupying much space, making it convenient to use.

[0033] Specifically, the ratchet wrench of this embodiment includes a ratchet 421 and a wrench 422. The ratchet 421 is fixedly sleeved on the screw 41, and the wrench 422 is rotatably mounted on the support sleeve 1. The outer end of the wrench 422 is a gripping end 423, and the inner end of the wrench 422 is provided with a groove 425 that can be fitted with the ratchet 421. A meshing block 426 is hinged in the groove 425, and the radial inner end face of the meshing block 426 is provided with a meshing block 426 that meshes with the ratchet. 421 forms a ratchet 4261 for meshing and linkage, and the ratchet 4261 is two segments arranged radially symmetrically. The center of the radially outer end face of the meshing block 426 is provided with a radially outwardly extending protrusion 4262. The bottom surface of the groove 425 of the wrench 422 is provided with a receiving hole 427. A steel ball 428 that can form a rotation limit with the protrusion 4262 is installed in the receiving hole 427. A compression spring is also provided between the steel ball 428 and the receiving hole 427.

[0034] As configured above, the engagement between the wrench 422 and the ratchet 421 is achieved through the engagement block 426. The ratchet teeth 4261 on the engagement block 426 engage with the ratchet 421, and the ratchet teeth 4261 on the engagement block 426 are divided into two symmetrically arranged segments, thus adapting to the forward and reverse rotation of the screw 41. For example, by operating the engagement block 426 to rotate in one direction, one segment of the ratchet teeth 4261 on the engagement block 426 engages with the ratchet 421, allowing the screw 41 to rotate forward when the wrench 422 is repeatedly rotated. By operating the engagement block 426 to rotate in the other direction, the other segment of the ratchet teeth 4261 on the engagement block 426 engages with the ratchet 421, allowing the screw 41 to rotate in reverse when the wrench 422 is repeatedly rotated. The engagement of the protrusion 4262 and the steel ball 428 allows the engagement block 426 to be positioned after rotation. When the engagement block 426 needs to rotate to the other side, the protrusion 4262 can press against the steel ball 428 to allow the protrusion 4262 to pass over, and the engagement block 426 can smoothly rotate to the other side. Then, the steel column is reset under the elastic force of the compression spring, thus positioning the engagement block 426.

[0035] To facilitate operation of the engagement block 426, a pressing block 429 is provided on the engagement block 426, extending through the groove 425 to the outside of the wrench 422. By operating the pressing block 429, the engagement block 426 can be rotated, achieving engagement and linkage with the ratchet 421 in different directions.

[0036] Specifically, the latch 5 includes a first arc-shaped plate 51, a second arc-shaped plate 52, a locking rod 53, and a locking nut 54 for locking the locking rod 53 to the second arc-shaped plate 52; one end of the first arc-shaped plate 51 is hinged to one end of the second arc-shaped plate 52, and the other end is hinged to one end of the locking rod 53; the second arc-shaped plate 52 is provided with a groove 521 adapted to the locking rod 53; the locking rod 53 is partially disposed in the first groove 521; the locking nut 54 is threadedly connected to the other end of the locking rod 53; and the locking nut 54 abuts against the second arc-shaped plate 52; the connecting rod 22 is connected to the first arc-shaped plate 51. In using the latch 5, first loosen the locking nut 54, rotate the locking rod 53 to the outside of the slot 521, then rotate the second arc plate 52 to increase the angle between the second arc plate 52 and the first arc plate 51, facilitating the installation of the latch 5 with the support rod. Then rotate the second arc plate 52 in the opposite direction until it abuts against the stage support rod. Then rotate the locking rod 53 in the opposite direction to the slot 521, and then tighten the locking nut 54 to complete the installation and fixation of the latch 5 with the support rod. The locking rod 53 and the locking nut 54 achieve relative fixation of the first arc plate 51 and the second arc plate 52. The hinge of the first arc plate 51 and the second arc plate 52 allows the latch 5 to be detachably connected to the support rod, making assembly flexible and convenient.

[0037] Specifically, the specific location of the ratchet fixing assembly 4 varies depending on the specific arrangement of the connecting rod 22 and the movable rod 21. For example, as... Figure 1-3 As shown, in this embodiment, the connecting rod 22 is threadedly connected to the support sleeve 1, that is, the connecting rod 22 is fixed to the support sleeve 1. The movable rod 21 can move axially relative to the support sleeve 1. The ratchet fixing assembly 4 is used to fix the movable rod 21. The movable rod 21 is provided with a strip groove 23 adapted to the screw 41. The screw 41 can be screwed into the strip groove 23 to fix the movable rod 21. Further, in this embodiment, the connecting member 6 is a connecting plate 63, and multiple connecting bolts 64 are installed on the connecting plate 63.

[0038] For example, in some other embodiments, such as Figure 4 and 5As shown, the connecting rod 22 is axially slidably connected to the support sleeve 1. The ratchet fixing assembly 4 is used to fix the connecting rod 22. The connecting rod 22 is provided with a strip groove 23 adapted to the screw 41. In this embodiment, the movable rod 21 can rotate relative to the support sleeve 1. The movable rod 21 is provided with an elastic locking protrusion 211. The support sleeve 1 is provided with a plurality of locking holes 12 along the circumferential direction for cooperating with the locking protrusion. The movable rod 21 is positioned by the cooperation of the locking protrusion and the locking holes 12. The user can operate the handle 3. The movable rod 21 is rotated, and after rotating to the correct position, the locking protrusion engages with the corresponding locking hole 12. In this embodiment, the connector 6 is a cross lock head 61 for engaging with the stage support. The movable rod 21 is also threaded with a locking nut 62 for abutting against the stage support. After the cross lock head 61 engages with the slot of the stage support, the locking nut 62 is rotated, causing the locking nut 62 to move towards the back of the stage support until the locking nut 62 abuts against the back of the stage support, thus achieving a stable connection to the stage support. The operation is convenient and quick.

[0039] This utility model is used for the connecting lock of stage support. By adopting the ratchet fixing component 4, it is easier for the staff to tighten or loosen the screw 41 to achieve the purpose of positioning the connecting rod 22 or the movable rod 21, which is convenient for users.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
